People and places

Law firms in Port Moresby are often more focused on the energy, projects and cross-border finance sectors than they are on intellectual property, which is no surprise given the country’s relatively small population – 9.2 million in 2022 – and small GDP of US$2,757 per capita in 2020. 

That said, there is effective IP legislation, an active IP office and the country is party to numerous treaties. In addition to the firms listed below, law firms in Australia may be able to provide some assistance.
